Quick answer: Every 20 minutes, look at something 20 feet away for 20 seconds. Blink fully, keep the screen an arm's length away and slightly below eye level, match brightness to the room, and keep your glasses up to date.
1. The 20-20-20 rule
Gives your focusing muscles a break.
2. Blink
We blink less on screens, which dries the eyes.
3. Distance and angle
About arm's length, top of screen at or just below eye level.
4. Lighting
Reduce glare; match screen brightness to the room.
5. Glasses
An outdated prescription causes strain.
